NO 1
Let y=(x^2+1)^(x^2)..add In 2 both
Iny=x^2In(x^2+1)..diff
(1/y)dy/dx=x^2(2x/x^2+1)+2xIn(x^2+1)
dy/dx=y{x^2(2x/x^2+1)+2xIn(x^2+1)}

Education › Re: Nairaland Mathematics Clinic by MrCalculus(m): 8:05pm On Jul 20, 2013

mathematician: doubledx u are totally wrong, now my working the eqn. 1/(cosx+1)² can also be written as (cosx+1)^-2, this means we have to use integration by algebraic subtitution. let u=(cosx+1), then du/dx= (-sinx), then then §(cosx+1)^-2.dx, becomes 1/(-sinx)§u^-2.du, after the integration we have /(-sinx)*(-u^-1) by replacing 'u' for its original value and multiplying, we have (sinx.cosx+sinx)^-1 + c or 1/(sinx.cosx+sinx)+c i hope u can see your mistake

Sir with all due respect dats not how 2 say a person is wrong,,i tink u should rephrase ur statement sir even though e is wrong or not

@OMOSIVIE
let d prob. dat d man leaves up 2 80yrs=P(M)=2/3
and d prob. dat e does nt=P'(M)=(1-2/3)=1/3.
let d prob. dat a woman leaves up 2 80yrs b=P(W)=3/5
and dat she does nt=P'(W)=(1-3/5)=2/5
: tongue

(@ least 1 leaves up 2 80yrs)=[P(M)xP'(W)]+[P'(M)xP(W)]
=[2/3x2/5]+[1/3x3/5]
=4/15+3/15=7/12
